When you have entered a wrong pin number three times the phone asks you for a PUK number. The PUK code is generally eight digit number. The PUK number is an unlocking code which helps you to unlock the phone and use it. If you enter a wrong PUK number 10 times than you simcard gets rejected. Then you will have to buy a new simcard. It might happen that your phone might ask you for PUK2 after you enter your PUK number. You can find the PUK code is in your SIM card documentation Starter Pack. If you do not have this then contact your phone service provider. Your cell phone service provider can give you the PUK code once they have confirmed your identity to prevent any stolen SIM access.

This problem is very common and most users think that it's related to phone, which is not true, this is only with your sim card and is for security reason. We can't use software or hardware or other tricks or methods to unlock it, the only solution is from the Service Operator/Network Operator.
If you keep entering random codes/unknown numbers several times, your sim card will be rejected and will not be usable anymore.

Your only solution is to call the service provider (Network operator's customer care), ask them to give you your puk code, they'll promptly give it to you after few inquiries to make sure you are the true owner of the sim card. (there's no charge as well, and if you call from the same network' sim card to the customer care, you'll not spend/pay a penny).

There's no other alternatives, or no other options that you can get the code, so don't play around, rather make a call to the customer care of the sim card network operator and get the code.

I wish you good luck.

Thanks for using FixYa.

tmobile gave me a unlock code that hasn't worked for me, but I'm not doing something correct. Feel free to take a shot at it: 0246813786538476

get it from ur service provider

the puk code is supplied by your provider after you have entered the wrong sim card pass code more than 5 time.
if i am understanding this correctly you actually need a PUK code.
You can either go to your provider store near you and they will unlock your sim or you can go onto their website and get a puk code, but not all providers offer the puk code over the net.

Seems Battery is not fully charged. Try to charge battery using universal charger then try to switch on the phone.

It is common that most mobile companies lock the phones to their networks. Several websites will be found to unlock the phones. Mostly it is paid service. Here are some links to unlock the phones.

I presume you mean for a phone?All questions need full 'make model (what it is)' as first 3 words please.The 'smart chip', normally referred to as a SIM Card comes from your cellphone service provider. It may already be locked to a particular telco and you can normally tell that when it boots up, or it is mentioned in settings.https://www.google.com/search?q=smart+chip+for+a+Sony+Ericsson..

Contact your service provider, they should know if you can change networks.It is a 2 & 3G only phone so that will restrict it as 3G is now obsolete.

What message are you getting on the screen when you turn the phone on? Is it recognising there is a sim card there but not letting you use it? The most common reason for this is often a 'Locked' handset. Most networks set the phones the sell to only work for their sim cards. Most specialist phone retailers can usually Unlock the handset for a small fee. If it isn't recognising that there is a card there it will either be a faulty sim card or a faulty phone.
